For what it's worth.... I love my 637, but quite honestly it's not something I want to bring to the range with four or five boxes of ammo. It does have a bit of recoil, but it'a not unmanagable by any means. I carry mine on a daily basis. I bring it to the range every once in a while to shoot my carry bullets through it, and then load it up with fresh ammo (about every three months or so). It's a very accurate little revolver. The 637 has an almost non-existant problem with bullet pull (compared to the lighter titanium pistols), but it can happen on occasion with light loads (115 grains or less)
Now.... With that said, I sent it back to S&W last Thursday for repair. The clearcoat was peeling off. I've read that S&W will always refinish these guns when the paint peels, and I've read that their service department is second to none. I'll let you know how I make out.... I've only owned it since January of '05. I don't use harsh cleaners like gun scrubber, but I carry it in a pocket holster and attribute the peeling (mostly on the backstrap) to other things in my pocket possably clanking against it.
Anyway... Its a great little revolver, and for about $350.00 new, it's a great deal. Go ahead and but it. Buy an Uncle Mikes pocket holster. It costs about $17.00 and it's a great way to carry the gun. It keeps it upright, protected, and keeps the revolver from printing. I hope this helps.... Rc
